<P CLASS=para>
The <tt CLASS=literal>PropertyEditorSupport</tt> class is a trivial
implementation of the <tt CLASS=literal>PropertyEditor</tt> interface.  It
provides "no-op" default implementations of most methods,
so that you can can define simple <tt CLASS=literal>PropertyEditor</tt>
subclasses that only override a few required methods.

<P CLASS=para>
In addition, <tt CLASS=literal>PropertyEditorSupport</tt> defines working
versions of <tt CLASS=literal>addPropertyChangeListener()</tt> and
<tt CLASS=literal>removePropertyChangeListener()</tt>, along with a
<tt CLASS=literal>firePropertyChange()</tt> method that sends a
<tt CLASS=literal>PropertyChangeEvent</tt> to all registered listeners.
<tt CLASS=literal>PropertyEditor</tt> classes may choose to instantiate a
<tt CLASS=literal>PropertyEditorSupport</tt> object simply to handle the
job of managing the list of listeners.  When used in this
way, the <tt CLASS=literal>PropertyEditorSupport</tt> object should be
instantiated with a source object specified, so that that
source object can be used in the <tt CLASS=literal>PropertyChangeEvent</tt>
objects that are sent.
